我正在嘗試配置traefik + docker，但是瀏覽器會永遠加載https url，你知道為什么嗎？

Question

我正在嘗試配置traefik + docker，但遇到了麻煩：瀏覽器會永久加載URL。 這是我的實際配置：

traefik.toml

debug = false

logLevel = "ERROR"
defaultEntryPoints = ["https","http"]

[entryPoints]

[entryPoints.http]
address = ":80"
[entryPoints.http.redirect]
entryPoint = "https"

# https is the default
[entryPoints.https]
address = ":443"
[entryPoints.https.tls]

[docker]
endpoint = "unix:///var/run/docker.sock"
domain = "cloud.castignoli.it"
watch = true
exposedByDefault = false

[acme]
email = "marco.castignoli@gmail.com"
storage = "acme.json"
entryPoint = "https"
onHostRule = true
[acme.httpChallenge]
entryPoint = "http"

然后，我有了acme.json ，實際上是treafik用正確的值填充的。

我正在嘗試為容器foo激活https，域為hello.cloud.castignoli.it foo僅具有此標簽

traefik.frontend.rule=Host:hello.cloud.castignoli.it

這些是traefik的日志

time="2018-10-11T08:04:50Z" level=error msg="Unable to obtain ACME certificate for domains \"reverse-proxy.traefik.\" detected thanks to rule \"Host:reverse-proxy.traefik.\" : unable to generate a certificate for the domains [reverse-proxy.traefik.]: acme: Error 400 - urn:ietf:params:acme:error:malformed - Error creating new order :: DNS name ends in a period"

這是traefik儀表板traefik的儀表板

問題與試圖為不存在的域生成證書的traefik的域有關。

在docker-compose.yml為您的域設置labels ，或者不要使用--api 。 例如：

  image: traefik
